Female Klingons are not attractive as a rule. But Worf's girlfriend and the mother of his child was. Unlike usual klingon females she had a nice row of straight shiny white teeth, instead of gnarled, yellow fangs. She had very little klingon features other than the hair and forehead. I just thought it was pretty bad how they made her look half human, cynical in a way. Why couldn't Worf's girlfriend be a typical looking klingon woman? Did they think it would make her harder to relate to or less tragic?
